1984kbps!!speedtest.net results after a couple of tweaks
i manually changed my prl using cdma workshop,added some build.prop 3g tweaks and i enabled 4gv vocoder and my download speeds are awesome.my download speeds before any tweaks was ranging from 300kbps to 400kbps and with tweaks applied from 1300kbps to 1984kbps all most 2mbs. Heres is a screenshot.
Tutorial
Tested on gingerbread should work on froyo but will not work on cm7. Disclaimer although all the tweaks listed here should not do any damage to your phone. if you do not know what your doing you may or can cause damage to your phone. do at your own risk.
• Enable 4gv= Go to your dialer and dial ##3282# enter your msl and you should see a data programming menu select edit you'll be prompted for msl again just re-enter it. Select advance and you should see something like this
change home orig.vcoder evrc, home page.vcoder evrc and roam orig.vcoder evrc to home orig.vcoder 4gv, home page.vcoder 4gv and roam orig.vcoder 4gv as shown below
Click home and reboot your device. Your upload and download speeds should increase as well as call quality.
Switch to a Sprint prl
All thanks to Koumajutsu for letting me use his tut
1) Turn on USB Debugging in the Settings > Applications > Development menu

__c) Enter your MSL
__d) Select USB
To change your phone to DM mode for gingerbread
__a)Dial ##7678#
__b)Enter your MSL

to test to see if my tweaks were working i removed all of them rebooted and my speeds were back down to 400kbs. added them back rebooted getting 1300kbs and up

I have no access to the hidden menu because I am running Hroarks Cm7 however I was able to get 2.18 Megs down using the 3g Turbocharger set to expiremental... Prl 60683 (with full service of course) ((and knowing boost full service is hard to come by in residential districts))

how do i know which prl i have and can you post the to 3g turbo?
go to settings > about phone > status .... If you dont know which prl you are on you are probably on the boost default one... changing to a sprint one (any sprint one) increased my service.. especially at home...

Having issues updating from a Boost PRL to a Sprint PRL, CDMA workshop won't read my phone at all, tried everything like suggested, device manager has two Samsung usb and modem devices listed, only one had a COM port assigned (8). Would connect but nothing otherwise.. Any suggestions? Or is there another way to manually change the PRL? Like some phones can actually just do it from a hidden menu

From step one to end would be Great for a tut. I am runnin Kuma Kournal, CTmod 2.3. I live upstate new york and running the stock boost prl and have no clue how to change it although I have seen a few steps saying how to do it, but not really understanding...

2) Odin your phone to EE14(Froyo). Which one doesn't matter, rooted/stock, all the same for this
3) Turn on USB Debugging in the Settings > Applications > Development menu
4) Change your "DM" mode to USB.
__a) Get your MSL: "adb shell getprop ril.MSL" (if you don't know how to use ADB, ask for help before following this)
__b) Enter the DM menu. (try placing a phonecall to "##8778#" no quotes)
__c) Enter your MSL
__d) Select USB
5) Open CDMA Workshop and select the serial port for your phone (In device manager, under Com ports, or Serial Ports, or something containing one of those words in the name, you might have to check the advanced tab for the device itself)
6) Click Connect
7) Under the security tab, Select Samsung (Sprint) for password (Samsung (Universal) on older versions of CDMA Workshop)
8) Click Send
9) On the Other Tab, click Send in the PRL box
10) Browse to the PRL file you downloaded elsewhere (I use 11115.prl, Google it ) and select it
11) Set your DM mode back to UART (See step 4)
12) Reboot your Phone.
* Froyo Users, you are Done, congrats!
13) Use ODIN to flash the backup you made in Step 1 back into your phone.
14) ???
15) Profit!
ron580: can you detail what values you tweaked in your build.prop?

komajutsu step 1-2 is not necessary if your on gingerbread. to get gingerbread on DM mode for cdma workshop to read it you will have to dial ##port# or ##7678# and select DM your phone will reboot in DM mode and cdma workshop should be able to read the phone now. and do you mind if i copy your tut ill give you all credit ill just add my info in step two. and ill upload my build.prop so you can check it out.

Go ahead, copy it, fix it, update it.
I just listed what I did. And I'm not familiar with the ## codes that work on our phone so I had no clue

I downloaded terminal emulator and found my MSL that way. Much easier that way. And I did end up finding the port. It was labled under modems > SAMSUNG modems. But if I have to lose all my stuff to change my PRL I'd just rather not. It was a hassel the first time to do it all because I'm not that tech smart to begin with.

GB CTMod 2.3 with Kouma 1.0 beta. This is all I know. A friend helped me set it up. I found my port. It's com4. I found my MSL number also. I Just have to search thru my computer for the adb file and see if I can piece this together, I did however change that EVRC-B and it didn't do anything so I believe changing my PRL will be the way to go. The only problem is finding one for upstate New York.

Thanks but i'm still having trouble getting adb from "one click root" to work and I can't find a cdma to download without strings attached. Any quick tips? I know I ask for a lot but i'm pickin up the pace and catching on so you wont have to tell me twice.
OK, so here is how I interpret what all these tweaks do.
Vocoder change: This changes the encoding algorithm for voice encoding, potentially freeing up bandwidth for data
PRL change: Allows roaming connections to more towers that are outside your base network. This will improve signal quality only when you just happen to be near a tower that you couldn't use before.
Build.prop tweaks: Makes changes to data encoding allowing your phone to use more of it's available signal bandwidth for data communications.
Another thing that might improve speeds is the proxy setting tweak found in another thread. Those instructions would be cool to consolidate with this thread's instructions
Ok i can rom the shit out of my phone easy, im using guide to change PRL but what prl what file lol anyone have this stuff. never used CDMA workshop before....so very interested in trying this
CTmod 2.3......CDMA workshop v3.2.6 from some site says www.cdma-ware.com on top
